This works for YouTube but not for YouTubeTV, correct? I find it not ideal that the iPhone Remote app can turn on AppleTV and TV, and sure I can navigate to the YouTubeTV app on the ATV, start a show, etc. However, once the iPhone Remote app transitions to the Dynamic Island or Lock Screen, there are 2 options: select remote and it’s back to navigating on the ATV (which works), or selecting YTTV will open the YTTV app on my phone, but that’s a second instance of YTTV on my phone with a separate stream. Ideally at that point via this workflow I would love the YTTV app on my phone to directly control the YTTV on the ATV. Does this make sense ?

Just to confirm your recommendation: when you say “matching on” do you mean “match dynamic range” and “match frame rate” set to on? And then format should be “4K SDR”?

I primarily have the latest higher end Samsung TVs last 2 years so I’m sure they support everything and I am using proper 4k HDMI cables. I primarily will use YouTube TV and AppleTV+ . I just want to make sure I am using the recommended settings (at least as a starting point).

I think this how that works based on the way the regular ATV remote works. At first I thought it was the proximity to a HomeKit mini, which I also have in each room but I believe Bluetooth is the answer.
